(A) Kaplan–Meier curve of recurrence data showing recurrence-free time after the first sudden sensorineural hearing loss episode. The recurrence-free (i.e., period of good hearing) rate was 69.9% over one year and 57.7% over two years; the median recurrence time for a subsequent sudden sensorineural hearing loss episode was 32 months. We used EZR ver.1.40 15 to create Kaplan–Meier curve. (B) Probability of recurrence over time. Logarithmic approximation (orange squares) of Kaplan–Meier graph for recurrence of sudden sensorineural hearing loss plotted along with the recurrence free rate (filled circles). The best fit value of K was .75, indicating that there is a 25% probability of sensorineural hearing loss recurrence every year. We used GraphPad Prism 9.0.0 for Windows, GraphPad Software, San Diego, California USA, www.graphpad.com to approximate the logarithmic model.
